When it comes to Sony's next flagship smartphone camera, bigger seems to be better. A supposed leak of press-ready imagery for the unannounced Sony Xperia Z5 names the camera at 23 megapixels, according to Xperia Blog, which says it obtained details and images.

Expected at the IFA electronics conference in Berlin next week, the camera could also pack in a 1/2.3-inch 23MP Exmor RS sensor. These are the makings for large, detailed, high-resolution photos from one of the best names in the smartphone camera business.

In an increasingly crowded and cutthroat phone landscape, Sony's camera credentials may not be enough to convince buyers. Although the company does forecast profit as it turns around its ailing phone business, new global phones from major players like Apple, Samsung and Motorola will apply pressure on the high end, while on the lower end, upstart shops like Xiaomi and OnePlus entice cost-conscious buyers with comparatively low prices on handsets with hardware features just shy of premium.
